In their own words,

Dominion Games is the creator of the Dominion Rules fantasy roleplaying system (DR). DR is a fast-paced, easy-to-learn, high-quality tabletop RPG distributed for free from this web site.

Some of the notably cool things this company has done are to create the world's only open-source RPG and to hire members of the Illuminator's Guild to illustrate it.
